To all whom it may concern:

Be it known that I, LEWIS G. LANGSTAFF, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Liquid-Dispensing Vessels, of which the following is a specification.

My invention relates to an im rovement in liquid dispensing vessels and as for its object to provide a very simple and effective device for insuring the delivery of a predee termined quantity of liquid from a vessel.

The invention is more particularly directed to vessels arranged to dlspense liquid soap.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fi ure 1 is a top plan view of my improved vesse and the means for supporting the same, Fig. 2 is a front view 0 the same, Fig. 3 is a vertical central section in the plane of the line A--A of Fig. 1, and Fig. 4 1s a detail section on an enlarged scale of the lower portion of the vessel and its adjacent parts.

' The vessel is herein represented of hol llohw, s

dispensing chamber 2 having a discharge port 3 which is o ened and-closed by a valve v4 as will hereina ter appear.

The bottom of the liquid dispensing chamber 2- in which the discharge port 3 is centrally located consists, in the present instance, of a cap having its upwar ed annular wall 5 provided with a screw threaded engagement with the'exterior wall of the liquid dispensing chamber 2. This cap is further provided with hand engaging lugs 6 projecting downwardly a distance below the head of the valve 4. The stem of the valve 4 is provided, adjacent to its head,

ly extend-- Patented Jan. 28 1908 to the vessel 1, which opening is normally closed by a sliding collar.

The stem of the valve 4 is secured within the lower end of the piston 10 by a cross pin 13 so arranged as to permit the valvegto have a limited lateral movement in all directions sothagt the valve may be at all times centered with respect to the discharge port 3 of the liquid dispensing chamber 2.

The piston head which, in the present instance is denoted as a washer 14, is supported between the bottom of the piston 10 and a collar 15 on the reduced p0rtion8 of thevalve stem. This washer 14 is ermitted a slight lateral movement in all irections with respect to the piston so that the said washer stance, a chain, one end of which is extended into the tubular bracket and is secured to a cross pin 17 fixed in the top of the vessel '1, the said cross pin extending through elongated slots 18 in the side walls of the tubular bracket, one of which slots is shown in Fi 3 The other. end of this chain 16 is extenr ed downwardly around a pulley 19 and from thence laterally over a pulley 20 beneath the floor where it is connected to the lower end of a spring actuated foot plunger 21, the foot iece 22 of which projects above the floor. his auxiliary lifting mechanism does not support the vessel, the entire weight of the vessel being supported, when in its normal lowered position, upon the hub of the valve 4 thus insuring an absolutely liquid tight closure of the liquid dispensing ch amber discharge port 3. The top of the vessel 1 ismere y guided in its vertically movable ad- 'ustmentson the tubular piston 10. It is .to

e understood that the interior of the piston 10 is in open communication with the interiorof the vessel 1, as, for instance, through openings 23.

Inv operation, when it is desired to dispense a portion of the liquid from within the vessel, the vessel is raised either by the engagement of the hand with the lugs 6 of the cap on the-vessel or by'depressing the foot plunger 21, 22. The first part of the upward movement of the vessel will serve to brin the washer 14 which forms thepiston hes.

" also always be centered with respect to the intjo lthe mouth of the dispensing chamber 2.

During thisp'ortion of the upward move- .ment of the chamber, the enlarged portion 7 of the valve stem will prevent the passage of the liquid through the discharge port 3. The

- further upward movement of the vessel will charge port and also that by giving the pistonhe'ad a limited lateral movementit will dispensing chamber thus absolutely preventing the cramping and binding of the'parts during their operation.

It is evident thatslight changes might be resorted to in the form, construction and arsaid valve rangement of the several parts Without departing from the spirit and scope of my in-- vention; hence I do not wish to limit mv'yself strictly. to the structure herein set forth, but What I claim is A 1. A vertically movable liquid containing vessel having a dispensing chamber and dis.' charge port therefor, a stationary piston and a discharge ort valve carried'by thev piston, eing arranged :to supportv the Weight of the vessel.

2-; A vertically movable-liquid containing vessel having a dispensing chamber and discharge'porttherefor, asta'tionary piston and a discharge port valve carried bythe. piston charge port therefor, a stationa movable laterally with respect t'othe piston, said valve being arranged to support the weight of the vessel.

3. A vertically movable liquid containing vessel having adispensing chamber and dis- I piston having a head arranged to enter sald dispensing chamber, said head being movable laterally with respect to the piston and a discharge port valve carried by the piston.

4. A vertically movable liquid containing vessel having a dispensing chamber and discharge port therefor, a rigidly figred piston having a laterally movable head arranged to enter said dispensing chamber, and a dischargeportzlvalve carried by the piston, said valve .being arranged to support the Weight of the vessel. V

5. A vertically movable liquid containing vessel having a dispensing chamber and discharge.v port there or,, a stationary piston having a head arranged to enter said dis? pensingv chamber and a discharge port valve carried by the iston, saidv head and valve being-movable iaterally with respect to the piston. I

. 6;, A vertically movable l-liquid containing vessel having a dispensing chamber anddischarge port therefor, a rigidly fixedpiston having a laterally movable head arranged to enter said dispensing chamber, and a laterally movable discharge port valve carried,

by the piston, said valve being arranged'to supportvthe Weight of the vessel. a

' v 7-. A vertically movable liquid containing vessel having a dispensing chamber and dis charge portv therefor, ahollow piston, a discharge port valve carried thereby, said-piston having a liquid filling hole exteriorgto the "vessel and an mdependentl movable collar \for opening and closing said ole.

. In testimony, that I claim the foregoing 'as my invention, I have signed my name in presence of two witnesses, this third day of October 1906. I
